CGS -21680 is an adenosine A2 receptor agonist with IC50 of 22 nM, exhibits 140-fold over A1 receptor. In an isolated perfused working rat heart model, CGS -21680 effectively increases coronary flow with an ED25 value of 1.8 nM. CGS-21680 binds adenosine A2 receptor with high affinity (Kd = 15.5 nM). Novartis originated CGS- 21680 in Switzerland and discontinued its development later.
